progressives, tom harkin, your home state senator from iowa, leading liberal in the senate, veteran senator. he has made clear he does not want that. he told me he may try to block a deal to stop it. >> unemployment benefits, the payroll tax holiday, the estate tax. the amt, the doc fix. it's more than just rates that we're talking about here, and it's more than just the sequester. there's all these patches. any clarity on those? >> reporter: you're absolutely right. there's so much. on the payroll tax, i have not heard anybody talk about continuing that. it doesn't mean it might not pop up at the last-minute, but what it means is that everything will see a little bit of a bite taken out of the paycheck no matter what because the payroll tax holiday gifforoes away. on the amt, many of us working the story at cnn were told they're talking about patching it that permanently.
